"Steve Ballmer had a dilemma. He had two groups at Microsoft pursuing competing visions for tablet computers. One group, led by Xbox godfather J Allard, was pushing for a sleek, two-screen tablet called the Courier that users controlled with their finger or a pen. But it had a problem: it was running a modified version of Windows. That ran headlong into the vision of tablet computing laid out by Steven Sinofsky, the head of Microsoft's Windows division. Sinofsky was wary of any product - let alone one from inside Microsoft's walls - that threatened the foundation of Microsoft's flagship operating system. But Sinofsky's tablet-friendly version of Windows was more than two years away." I'm still mad at Microsoft for this one.
